.: The Necessity of Evaluating the Effectiveness of Wearing the Face Shield With a Mask Only on the Mouth,as a Kind of Physical Precluding to Combat New Coronavirus Outbreak The Necessity of Evaluating the Effectiveness of Wearing the Face Shield With a Mask Only on Kamyar Esmaeil M.D.,Integrative Medicine,Tehran-Iran newstructure1@gmail.com Received: June 2023 Accepted: August 2023 Abstract Given the prospect of Covid-19 outbreak,successive mutations,and the relative and temporary effectiveness of the vaccines,taking health-oriented measures with participatory and proactive approach is required. Along with the measures like vaccination,"physical precluding" should be considered as well. - The transmission capability of some new variants of SARS-CoV-2 is substantially high,and an increasing reduction in the effectiveness of solely using face masks is alarming. Wearing a face shield with a mask that covers both the mouth and the nose under the shield is an effective method of physical precluding in usual spaces; but it is not a practical method for many people. Instead,wearing a face mask that covers only the mouth under the shield can make it easier. - The most important function of the mask under the shield is to reduce the amount and also the "velocity" of the particles that come out through the mouth. By "reducing the amount and velocity of such particles (by wearing a cover on the mouth under the shield)" and considering "the function of the shield placed in front of the cover" and "the key role of larger particles in the Covid-19 transmission",it is expected any risk of the problematic particles that could come out from around the shield be decreased. - About this,performing a simulation to evaluate the effectiveness of wearing the face shield together with various disposable and washable masks (such as economical cloth covers) that only cover the mouth under the shield,as a facilitated method of physical precluding by the public,is recommended.
